“…Triglyceride levels were lower in non-spayed females in all BCS groups; however, no statistically significant difference was observed. These results corroborate what has been described in similar situations (15) . Our results were considerably higher than those described by Brunetto et al (21) , who found 89.3 mg/dL and 56.4 mg/dL of triglycerides for obese and normal dogs, respectively.…”

“…The behavior of cholesterol parameters did not differ among weight classes, contrary to what is usually observed in humans (20) and, occasionally, in dogs (13,21) . On the other hand, our results seem to corroborate what is usually found in this species (22,15) . Likewise, cholesterol values did not vary among spayed and non-spayed dogs, contrary to the observed effects of menopause in women (2) .…”

“…This result is expected, since one of the effects of estrogen is keeping LDL at normal levels (23) . The overall results were within normal limits, and similar to what has been described fro dogs (15) and post-menopausal women (24) . Barrie et al (14) found markedly lower LDL values in normal and obese dogs (30.96 mg/dL and 33.84 mg/dL, respectively); however, they were assessing dogs suffering from diabetes, hyperadrenocorticism and hypothyroidism.…”

“…Lower levels have been described in healthy, eutrophic (42.12 mg/dL) and obese (62.46 mg/dL) dogs (14) ; however, these were also within normal limits. Lower HDL levels in spayed, compared to non-spayed, females has been described (15) with a 1.87 times decrease one year after spaying. The results described here also mirror the lipoprotein patterns seen in post-menopausal women, who show a progressive decrease in HDL (16,17,18) .…”

Serum Lipid Profile of Spayed and Non-Spayed Female Dogs Associated With the Body Condition Score

et al. 2015

Neutering females may be associated to weight gain in dogs. In order to diagnose possible alterations, such as diabetes and hyperlipidemias, laboratory assessment of carbohydrate and lipid metabolism is important. The aim of this study was to verify glycemia and serum lipid profile in non-spayed and spayed female dogs, and associate these results with the body condition score. Thirty-two spayed (n=16) and non-spayed (n=16) female dogs had their blood collected for biochemical analysis, and were classified as to their body condition score (BCS). Nine had normal BCS, 10 were overweight, and 13 were obese. Little difference was observed among spayed and non-spayed dogs. Glycemia of spayed canine females is higher than that of non-spayed dogs, regardless of the body condition score. Likewise, total cholesterol levels are higher in non-spayed females. The HDL is higher in non-spayed obese dogs than in spayed dogs with the same body condition, this parameter did not differ in other weight groups. Contrary to what happens in post-menopausal women, spaying dogs does not seem to have such a strong effect on the metabolic parameters assessed. This study revealed unique results, where neither spaying nor weight group had a strong association with metabolic alterations.

“…Hyperlipidaemia was more prevalent in castrated animals (70%) of this study. Schmidt et al [ 28 ] suggested that plasma TG concentrations in hysterectomized females tend to increase, however Xenoulis et al [ 8 ] did not as a predisposing factor for idiopathic hyperlipidaemia.…”

Supplementation of omega-3 and dietary factors can influence the cholesterolemia and triglyceridemia in hyperlipidemic Schnauzer dogs: A preliminary report

et al. 2021

Primary hyperlipidaemia in Schnauzer is characterized by increased plasma triglycerides (TG) and/or total cholesterol (TC) concentration and is associated with an increased risk of developing pancreatitis, insulin resistance and seizures. In humans, omega-3 fatty acids in addition to a low-fat diet can be used to reduce TG and TC. This study evaluated the therapeutic efficacy of omega-3 fatty acids associated to a diet management with two different fat content in Schnauzer with primary hyperlipidaemia. Eighteen dogs with primary hyperlipidaemia were divided into two groups: group 1, n = 10, 8 females, 2 males, age (mean ± standard deviation) of 7.13 ± 2.70 years and body weight (BW) (mean ± standard deviation) of 7.25 ± 1.22 kg were treated with fish oil (approximately 730 mg/day of omega-3) associated with a low-fat and low-calorie diet (approximately 24g of fat/1000 kcal) for 90 days (T90); and group 2, n = 8 dogs, 6 females, 2 males, with 7.0 ± 1.77 years old and average BW of 8.36 ± 1.51 kg, treated with fish oil (approximately 730 mg/day of omega-3) and maintenance diet with moderate amount of fat (approximately 33g of fat/1000 kcal) for 90 days. Plasma TG and TC concentrations and lipoprotein (LP) profile (VLDL, LDL, HDL) were evaluated before and after treatment. TG and TC serum concentrations, expressed in mg/dL (mean ± standard deviation), before and after treatment in group 1 were: TG = 391.30 ± 487.86 (T0) and 118.7 ± 135.21 (T90); TC = 308.2 ± 63.06 (T0) and 139 ± 36.91 (T90). As for group 2, TG = 391.63 ± 336.89 (T0) and 250.75 ± 211.56 (T90); TC = 257.25 ± 92.88 (T0) and 207.25 ± 63.79 (T90). A reduction (p<0.05) of TG and TC was observed in both groups. The distribution of TG and TC among LP was not different between the pre (T0) and post treatment (T90) periods. After 90 days of treatment, the administration of omega-3 fatty acids, associated with a low-fat or maintenance diet reduced triglyceridemia and cholesterolemia without altering LP profile. The current investigation shows that both therapies were effective in reducing plasma TC and TG concentrations without altering LP profile.
